Under the agreement, BMW will gain access to Solid Power’s battery research and development, cell design, and manufacturing expertise to expedite the technology alongside its partner. That being said, Solid Power isn’t licensing all of its technology.
BMW, an investor in Solid Power, already has an agreement to receive finished battery cells. Solid Power, which went public in December last year, is among a group of companies trying to create next-generation batteries for electric vehicles, aiming to solve some issues related to lithium-ion batteries that are currently is use.
This morning, Solid Power announced that long-time investor BMW Group is expanding an existing joint development agreement to license its technology in order to build its own solid-state batteries in Germany.
By gaining a license to Solid Power’s research and development, cell design, and manufacturing practices, BMW Group intends to duplicate Solid Power’s pilot production line at its own facility in Germany in order to produce prototype batteries cells of its own.
To do so, the BMW Group will develop innovative production processes and systems, which will then be installed at the 14,000 m² pilot plant. Using production processes and systems also employed in standard production, the company will be able to demonstrate the industrial feasibility of future battery cell generations.
REUTERS/Bob Strong Purchase Licensing Rights Dec 21 (Reuters) - Solid Power Inc (SLDP.O) said on Wednesday it will offer some intellectual property rights related to its solid-state batteries to BMW (BMWG.DE) and allow production of the battery cells at the automaker's facilities in Germany.

The primary use for betavoltaics is for remote and long-term use, such as requiring electrical power for a decade or two. Recent progress has prompted some to suggest using betavoltaics to conventional batteries in consumer devices, such as and . As early as 1973, betavoltaics were suggested for use in long-term medical devices such as . The process is similar to how solar panels (photovoltaics) convert sunlight into electricity, but instead of capturing energy from the sun, betavoltaic batteries harness energy from beta particles —high-speed electrons released during the decay process.

The purpose of beta-voltaic batteries is to generate power from isotope decay energy. These batteries' primary components are a semiconductor structure that transforms the kinetic energy of beta particles into electrical energy and a radioisotope source.
Rappaport's iteration of a betavoltaic cell delivered 0.8 μW of electric power from a total 200 μCi of radioactive power emitted by the source, giving a cell conversion efficiency of 0.4%. Rappaport found that an optimized wafer of the same design has the potential to produce electric potential with an efficiency of 2%. [4,5]
High energy density, long service life, and miniaturization to fit on a chip give betavoltaic batteries some advantages over chemical batteries. The working principle of a betavoltaic battery has both similarities and differences with photovoltaic cells and radiation detectors.
The research of betavoltaic battery involves many aspects, including battery miniaturization, theoretical calculation of output performance, optimization design of nuclear battery structure and laboratory testing of battery samples, etc.
However, in comparison to other battery types, beta-voltaic batteries have a very high energy density, that is, the total amount of energy the battery stores per unit of mass—despite having a relatively low power density, as seen in Fig. 15.
A betavoltaic device (betavoltaic cell or betavoltaic battery) is a type of nuclear battery that generates electric current from beta particles (electrons or positrons) emitted from a radioactive source, using semiconductor junctions. A common source used is the hydrogen isotope tritium.

Batteries are becoming more and more popular to pair with solar. But should you install one now or wait? Learn what to consider to decide.. Are you wondering if you should invest in a battery for your solar energy system? This article explores the pros and cons of adding a battery, from storing energy for nighttime use to providing backup power during outages.. Ask your solar installer if they can add a battery to your system. If you purchase a battery on its own or a solar-plus-storage system, you will be eligible for federal tax credits.. If you're installing a solar battery at the same time as solar panels, it's best to opt for a DC battery, which connects directly to your panels and doesn't require an additional inverter.. Thinking about adding a battery to your solar system? Learn how it can boost savings, add backup power, and make your setup more efficient. [pdf]
